MODULOR
Athlete Brief · v1.0

Built for athletes who are tired of guessing whether they're getting tighter or looser.

Modulor is a cable-driven stretching platform that pulls your limb through a controlled stretch, measures exactly how far you went, exactly how much force it took, and shows you whether your left and right sides match. Every session is a measurement. No therapist guessing pressure. No goniometer. No "how does that feel?"

Why we're sending this to you: you're an athlete whose career depends on staying available. We're building this for people like you and we want your honest reaction before we ship.

What it does in plain English

You lie or sit on a padded platform. A motorized cable attaches to a soft cuff on your ankle, wrist, or whichever segment is being stretched. The machine pulls slowly — you control how hard, in pounds, on a touchscreen — while a depth camera watches your body. It stretches you to your actual end-range. The moment your pelvis or trunk starts compensating, the force backs off automatically. You finish, you see your numbers, you go.

What it actually measures

  • Range of motion at a fixed force (your real flexibility)
  • End-range stiffness (how hard the tissue resists)
  • Left-vs-right asymmetry (the #1 hamstring re-injury predictor)
  • Whether you're trending up or down session-over-session
  • Composite injury-risk score

Why it matters for your sport

Hamstring strains are 24% of all injuries in pro football and have doubled over 21 years. ACL risk tracks ankle dorsiflexion. Adductor strains in basketball and lacrosse follow groin asymmetry. Today, performance staffs measure none of that with any precision — they use a hand-held protractor and their eyes. We measure all of it, every session.

Time per session

Bilateral baseline + assisted stretch + report = under 8 minutes. Setup <45 seconds. Designed to fit between weights and practice, not replace anything in your routine.

What it feels like: Imagine a manual stretching session with a therapist who has perfect, repeatable hands, never gets tired, and shows you exactly how much further you went than last week. The machine yields the instant you start cheating. It will not push you past where your body is willing to go — that's the point.

What I'm asking from you

20 minutes of your honest reaction. Read this, look at the website (link below), and tell me: would you use this — and if not, what would have to be different? If yes, would you let us put a unit in your team's facility for a 6-week pilot at no cost? You'd be the first athlete in your sport on the platform and you'd shape what we build next.
